Hines says he doubts whether fisheries regulators can control the catch well enough with such measures. He believes crabs would be better protected by putting major sections of the bay off-limits to crabbing, and by reducing the number of crabbers and the amount of gear they can use.
For its part, Virginia has established a crab sanctuary, closing a vast expanse of water to harvest in the spring when crabs begin spawning in earnest. The state also reduced the number of crab pots its watermen could use, and it might order a further reduction this year if the crabs are not recovering adequately, said Jack Travelstead, Virginia's fisheries director.
Scientists do not agree on the best way to proceed. Miller says a sanctuary makes sense in Virginia, where research has identified crabs' spawning area. Similar closures here would be less effective, he said, because less is known about migration routes.
